CABLE TESTING
Cable Testing Guidelines
The Cable Prowler tests coax, network, and phone cables to detect possible
faults, measure cable lengths, show wire pairing and examine a cable’s
physical/electrical properties.
Important Notes:
• RJ jacks for data and phone share internal connections on the
Cable Prowler. Connect just one RJ cable at a time.
• You cannot connect an RJ and coaxial cable at the same time.
• If testing RJ cables, remove any coax cable adapters
Safety Notes
The Cable Prowler is designed for use on cables with voltage below 60V.
Do not plug the device into a source with voltage above 60V. Connecting
the device to live AC power can damage the unit and pose a safety hazard.
Poorly terminated RJ plugs can damage the jacks on the Cable
Prowler. Inspect all RJ plugs before inserting them into the Cable
Prowler. Make sure you insert the plug into the appropriate jack
of the remote or device.
Cable contacts should be recessed into the plastic housing of
the receiving jack. Don’t plug a six-position phone plug into an
eight-position data jack on a remote or remote device.
Length Testing
Cable Prowler measures cable length and length to faults using Time
Domain Reectometry (TDR). Velocity of Propagation (VOP) is the TDR
measurement of the speed of the reected waveforms compared to the speed
of light. VOP values can vary among cable types, lots, and manufacturers. In
most cases, these differences are minor and may be disregarded.
Cable Testing with Remotes
Network/Tel Cable Prowler remotes are used to verify connectivity at
the opposite end of a cable and provide an ID. To connect to a telephone
cable, use the included RJ12 no fault telephone patch cables to connect to
a RJ11 wall plate. The Coax ID remotes and Network ID emotes are used
to provide an ID only.
